Application med June 22, 1926*. serial Np. 117,787.

Thisinvention relates to certain improvements in cooling and fillingcaps for radiators; and the nature andfobjects of the invention will bereadily recognizedl and under- 5 stood by those skilled in the art inthelight of the following explanation and detailed `de-` scription ofthe accompanying drawings illustrating what I at present consider to bethe preferred embodiment or mechanical expressions ofthe invention fromamong various other form-s, arrangements, combinations and constructionsof which the invention is ca-y pable within the spirit and scopethereof.

The invention is particularly directed to the provision of a cap orclosure for the filling neck or opening of a motor vehicle radiator, andpresentsas one `of its main objects and characteristics a designandconstruction of such a cap or closure by which the more rapid coolingof the water or other liquid in the radiator can be secured to pre-ventoverheating ofthe motor cooled by such liquid, and to further providefor ready opening of .the radiator filling neck to permit ofreplenishing or filling the radiator with lcooling A further objectofthe yinvention `is to provide a cap or closure vfor thel filling neckor opening of a motor vehicle radiator, which is formed With avariableopening or port therein through thek medium of which the in# terior oftheiradiator caribe opened to atmos-` phere (iliurinjg movement of amotor vehicle to cause tlow of air intor the radiator to assistv n ingspurely by wayof example andpnot of rlimitation to permit of' explainingthe prinin rapid cooling of the liquid therein.

Another object of the invention is to provide a fillingcap or yclosure'for amotor vehicle radiator with a port or opening through a sidethereof, togetherl with means for open- 40 ing or closing the opening,or varying the area thereof opened, tok assist in cooling jthe liquid inthe radiator by discharge of air thereinto, as Wellas to provide such adevice with a removable cover or headto permit of illinglthe radiatorwith liquid.

Another object of theinventionhis to pro -l vide a cooling and fillingcap for motor vehicle radiators embodying the above mentionedcharacteristics, which cap isadapted for application to and use on andwith all types ofwater or liquid cooling radiators for ,motorfvehicles,and which is of simple deand construction capable of manufacture inquantities at relatively small cost,v and positive;v and eiicient in,operation with a mini- .55 muni of attention and upkeep required .inv

- use.

With the ,foregoing general objects, certain other objects and resultsin y yview* which will be readily recognized by those, familiar withthis art from `the following explanation, the invention consists incertain novel .features in construction and kin combination andyarrangement of parts, asy will'k be more fullyand completely referredtoand specified hereinafter; 4. n l

`One possible embodiment of which rthe in;l ventionl is capable, ispresented in thedrawciples and Ivarious features of the invention, butit is to be understood, as will be obvious from they followingdescription, that the invention can be mechanically expressed in other`forms and by other lconstructions,than the specific` example hereshown. Y VAccording to the invention, a casing or body .l0 isyp-rovidedwhich in the example hereof `is tubular in form having an open top, anda downwardlytapering, funnel shaped lower or bottom wall 11, terminatingin the depending, `externally screw threaded dischargegneck 12, ofreduced diameter with `respect to the body or casing. l0'.l rlhe open,upper end of the casing l() is externally screw threaded, and isnormallyclosed by the ref movable top or cover i4 threaded thereon. Thetop lfl, in this-instance, although. not so limited, is provided with acentral aperture 15 forming a socket for receiving the supportv for anysuitableornament sueltas-a fla-g, which it may be desired to carry withthe cap'of the invention mounted on a radiator. rIhr'ough the side ofcasing 10 betweenthe upper end thereof and the contracting bottom wall11, a port or opening `16 is provided, which in the example here shownis of a width approximating the diameter or width of Casin(Y 10. so thatthe Jort is of substan-` tial area and lextends across one -side ofvthe,`

- casing.

At the lower end of casing -10 at its junction with the bottom wall 11,a circum-ferential bead or shoulder '17 is formed around the exterior ofthe casing, and v`sleeve or band 18 is fitted over and around theexterior of thecasing 10 for rotation thereon and thereaiound. The band18is confined on the casing 10 against downward displacementV by the'shoulder or bead17 on which it bears, and extends upwardly to the loweredge of the cover 14, being preferably spaced slightly therefrom. Thewidth of band 18 is thus such that it covers the port or opening 16through the casing'lO, and the band forms a suiiiciently tight titv withand on the casing that it will not readily rotate therearound fromvibrationbut can be manually or positively rotated on and around thecasing to any desired position. The band 18` is provided kwith a port oropening 19 there#r through of the same size and yarea as opening 16through the casing and by rotatingband 18 can be positioned to registerwith 'casing port 16 and forman opening from atmosphere to the interiorof the casing, or the band can be rotated to move port 19 from registrywith port 16, with the bodyof the band over and closing the latter port,as will be clear.

In operation and use vof the radiator coolin r and filliiw ca 9constructed and arranged b D 2D as above described, referring vnow toFig; 1 of the accompanying drawings' 1n particular, the cap is mountedon a motor vehicle radiator R by screwing the discharge neck 12'of' thecap downwardly into the filling neck or opening F of the radiator, withthe casing 10 of the cap disposed in position above the radiatory incommunication therewith through neck 12. The cap is positioned on .theradiator R with the port or opening 16 through casing 10 disposed at theforward side in the direction of airow pastthe radiator witha vehicle(not shown) on which vformed by registered ports 16 and 19,

through casing 10 and into the radiator and assists the cooling of theradiator liquid. rIhe area'of the opening thus formed can be regulatedor adjusted as desired by the extent fthe ports 16 andr19., are placedin registry.

W'hen it is desired to shut off air flow and closethe opening to theradiatoi'band 18 is rotated to place ports 16 and 19 in non-registrywith v the band port 16.

If desired or found expedient the'band or over and closing casing sleeve18, is .provided with any suitable screening or the lil-:e-20,"toprevent entry of foreign matter of an objectionable size into theradiator with the band in position forming a passage orl opening throughthe' cap to the radiator." A portion of the screening 20'is shown'inFig. Q of the drawings byway of example, but* the invention contemplatesand includes, as the equivalent thereof, the formation of a *seriesof'apertures through sleeve or band 18 for registry with or position overthe casingopening, in place of the port 19l and the screening y2Othereover, as will be clear Vand understood by those skilled inthe art.

- A'further feature and function of the in-` vention is that ofproviding a filler cap for the radiator.v The form of the casing 10 withbottoni wall 11 and'contracted discharge neck 12, provides in effect afunnel, so that by removing the cover 14 of the casing the radiator canbe quickly 'and easily filled with liquid vor 'the liquid replenishedwithout spill-p ing as is usually thev case when it is necessary toypour the 'liquid through the restricted opening formed by thefillingneck F of the radiator. vIn this way the necessity forearryin gor employing a funnel lfor luse in fillinga radiator'4 is ydone awaywith as the radiator cap of the invention provides therefor. f If it' isnot vdesired to remove cover 14:, it is possible to pour liquid into theradiator through the y opening formed by the ports 16 and 19 inregisti-y, by the use of a spouted container and in this way avoidreinovin any velement from the radiator, withv possibility of loss'ormis-l placement.- 'j 'i Itis evident that various changes,modifications, variations, and'substitutions might be resorted towithout departing from the spirit and scopefof my invention, and hence I'do not desire to limit myself lto the exact and specific disclosureshereof. ,v c Desiring to protect my invention in the `broadestmannerglegallypossible, whaty I claim is: j v v l j 1. In a radiatorcap, a; casing'formed with a port therethrough, and av sleeve rotatablymounted varound said jcasing over the said port to adjusted positionsthereon,;said sleeve formed with a port therethrough for adjustedregistryk with said casing port to form an air passagepof desired area,and the said sleeve rotatable to retained position with the port thereinin non-registry With said easing Y port With the sleeve closing theCasin g port'.l

2. In a radiator cap, a tubular Casing for mounting on and incommunication With a radiator, a removable cover Jfor said casing, and avalve sleeve rotatably mounted on and around said easing, said easingformed with a port therethrough, and the sleeve formed with a porttherethrough, the sleeve rotatable to place said ports in the desiredextent. of registry to form an air passage through the eap of thedesired area, or to place the sleeve port in non-registry with thecasing port to completely close the air passage.

3. In a radiator' cap, a tubular easing formed with a reduced lower endforming a discharge neel; for mounting in the filling neel; of aradiator, a oever for the upper end of said easing, the easing formedwith an opening through a side thereof, a sleeve rotatably mountedaround said easing for normally closing the easing opening, the saidsleeve formed with an opening therethrough for registry with the easingopening by rotation of said sleeve, and the said casing forming a funnelfor fillinga radiator with thecasing oo ver removed.

4l. ln combination With a motor Vehicle radiator' and the lilling necktherefor, a tubular easing having a reduced diameter lower discharge endfor removably itting into the radiator illing neel; with the easing incominunioation with the radiator, said easing forming a filling funnelfor the radiator, a removable cover for closing the upper enlarged endetthe easing, the easing formed with an opening at the forward sidethereof separatetrom the open upper end of the cas* ing for passage ofair into the radiator, and means ior opening and closing said casingopeningfto vary the size thereofV and control passage of' airtherethrough.
